I’m not sure of your specific question. If you’re asking if you’re likely to be approved, I’d say it’s a slam dunk although it might require a recon call to reallocate credit limit(s) if they don’t offer online during the application.

I do not believe one can have 2 identical Chase consumer cards at the same time. I do not believe Chase will approve an application if one has an existing open identical card (account). I do not know the recommended duration between cancelling the old card and applying for the new card. I’ve read here that some advocate 1 week, I suggest at least 1 month mainly to not upset the Golden Goose (Chase) although I've not done it myself for several years.
